In an experiment, the researcher is trying to examine the effects of artificial sweeteners on the germination of radish seeds.  She gives the plants in Group A sugar.  Plants in Group B receive NutraSweet.  Plants in Group C get Sweet & Low.  She finds that those in Group A have the longest roots after two weeks.  There is also a group D.  What is the dependent variable?

Species fit along a continuum of r- and K-selection; not all species show purely r traits or purely K traits. For example, sparrows produce several young per year but only live a few years, while the wandering albatross first reproduces at age 10 and then produces a single egg every other year during its 40-year life span. Compared to the albatross, the sparrow is more

Note: same information for questions 16-19. The following figure shows the production possibilities frontiers of two countries, Home and Foreign (solid lines). They produce two goods, Oil and Cars. Also shown are two indifference curves for the Home country. When the two countries open up to free and costless trade with each other, the resulting price line for the Home country is also shown as the dashed line. HOME has comparative advantage in

Note: same information for questions 16-19. The following figure shows the production possibilities frontiers of two countries, Home and Foreign (solid lines). They produce two goods, Oil and Cars. Also shown are two indifference curves for the Home country. When the two countries open up to free and costless trade with each other, the resulting price line for the Home country is also shown as the dashed line. When there is free and costless trade between the two countries, how many units of Oil will FOREIGN consume? Enter 0 if not enough information is provided. Only exact answer is accepted. Use a decimal point if needed.

Note: same information for questions 20-25, except where otherwise noted. A small country is engaged in free international trade with a large country. There are two sectors (goods): sector (good) x and sector (good) y. There are three factors of production: labor, which is perfectly mobile across the two sectors; land, which is specific to good x; and capital, which is specific to good y. The solid lines of the following figure represent: Px MPLx for the small country as a function of Lx, measured from origin O; and Py MPLy as a function of Ly, measured from origin O*. The length of the base of the figure is L=2000, the total units of labor in the country. One unit of labor is one worker working for a year. The scale on the vertical axis is thousands of dollars. Note that each grid spacing on the horizontal represents 50 workers, and each grid spacing on the vertical axis represents 1 thousand dollars. NOTES:            – Ignore the dashed line until it is mentioned below. – Since this is a graphical question, some of the answers may be approximate! For all remaining questions in this group, suppose that labor can move freely from one sector to another. For the remainder of this group, suppose that the price of good y doubles, resulting in the dashed line, labeled P’y MPLy. After the price of good y doubles, approximately how much is the new wage in the country?

To explain this, we need to understand that ______ .
